    Downpipe w/high flow cat

    Ok, so I bought my 2003 wrx with a 3" catless downpipe to a 3" Borla cat back exhaust. I was thinking about replacing the downpipe it has now with an Invidia downpipe with a high flow cat from This is a direct bolt on mod correct? I will just need the downpipe, a new turbo to downpipe gasket, and a new downpipe to exhaust gasket? I figure it will fit correctly but im just not ready to spend around $500 without being absolutely sure. Any input would be nice... thanks

    Invidia Downpipe
